<p>[QUOTE=&quot;desertgem, post: 4586760, member: 15199&quot;]It appears to just be an acid solution. The MSDS suggests by the pH and boiling point, it is just a weak acid ( pH4.0) and the density of 1.05 and Flash point of &gt;93 degrees C. that most of the liquid is water. European products do not give as much details on MSDS forms as in US. Maybe there are other chemicals in it, but nothing very active or it would be listed.</p><p><a href="http://www.kremer-pigmente.com/media/pdf/62902_SHD_ENG.pdf" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.kremer-pigmente.com/media/pdf/62902_SHD_ENG.pdf" rel="nofollow">http://www.kremer-pigmente.com/media/pdf/62902_SHD_ENG.pdf</a></p><p><br /></p><p>Pre-Lim MSDS is also lacking in details. A Renaissance wax product that is &quot;38% non-scratching abrasive&quot; , but they do not give the material used so one can see the Moh Hardness number. Since they also recommend as a car-cleaner before waxing, I suspect they mean &quot;no obvious scratching&quot;, so I can&#039;t find much. I use extremely fine grit when I facet gemstones and no scratches are visible to the naked eye or a 5x magnifier, but under a 30X, they are seen. Do a coin and send it to ICG or ANACS ( because they are less expensive and see if it gets detailed)&nbsp;&nbsp; Kentucky found the MSDS already <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>IMO,</p><p>Jim[/QUOTE]</p><p><br /></p>
